Abstract
With regard to an index in relation to organic carbon content in order to suppress high concentration hydrogen sulfide generation at solid waste landfill site, it is necessary to estimate an effectiveness of an index concidering utilization rate of organic carbon, rather than total organic carbon (TOC) which doesn't distinguish easily decomposable and refractory organic carbon. In this study, potential of hydrogen sulfide generation with extraction liquid from wood, i.e., cellulosic organic carbon was measured and compaired with the potential with easily decomposable organic carbon (microorganism culture medium) which was obtained by previous study. The potential with extraction liquid from wood was smaller than that with microorganism culture medium at same TOC. If the standard for suppression of high concentration hydrogen sulfide generation was established by TOC, wood had to be removed excessively from a solid waste. High concentration hydrogen sulfide was not generated from extraction liquid from wood and microorganism culture medium at less than 0.3 mmol-O2 / (L·h) of oxygen consumption rate.
